A mock wreck and emergency response will be carried out at the Coastal Carolina Fairgrounds Tuesday to show teen-age drivers the dangers of driving under the influence of alcohol.

"Operation: Prom Promise" is scheduled from 9 a.m. to 2 p.m., according to Capt. Chad Kelly of St. Johns Fire Department, which is coordinating the event.

Other agencies involved are the Isle of Palms Fire Department, S.C. Highway Patrol, Charleston County Sheriff's Office, C&B Fire Department, Charleston County Rescue Squad, North Charleston Police Department, City of Charleston Police Department, Teen CERT, Charleston County Coroner's Office, Coastal Crisis Chaplaincy, Charleston County EMS and Med-Trans Air.

Cars are being donated by Auto Salvage Company of Ladson and LA Motors Towing.

The event will start with a 911 emergency call to a mock vehicle accident. Responders will treat the scene like an actual accident.

Students involved in the demonstration have been pre-selected by the Teen CERT program, and parents of these students have been notified, Kelly said.

The event will be filmed. The film will be used in schools during a mock DUI trial with actual judges and attorneys who have donated their time.
